1. The plaintiff's claim is dismissed.

2. The defendant shall pay to the plaintiff's successor KRW 41,263,00 and KRW 39,447,17 among them.

In full view of the purport of the arguments in Gap evidence Nos. 1 through 6, the defendant entered into a loan agreement with the plaintiff on May 31, 2018 to grant a loan of KRW 50,00,000 from the plaintiff at the interest rate of KRW 15.9%, overdue interest rate of KRW 18.9%, and the period of 48 months. The amount of the debt principle under the loan agreement of this case reaches the total amount of KRW 41,263,00 (the principal amount shall be KRW 39,447,177) as of January 8, 2020. The plaintiff entered into a contract with the plaintiff's succeeding intervenor on May 26, 2020, and the plaintiff's succeeding intervenor transferred his claim against the defendant under the loan agreement of this case to the plaintiff's succeeding intervenor, and the plaintiff's succeeding intervenor notified the defendant of the transfer of the above claim with the authority delegated by the plaintiff.

According to the above facts of recognition, the defendant is obligated to pay the plaintiff's successor losses calculated at the rate of 18.9% per annum, which is the overdue interest rate of 18.9% from January 9, 2020 to the date of full payment of the principal amount of KRW 41,263,009 and the principal amount of KRW 39,447,177.

Therefore, the plaintiff's successor's claim of this case is justified, and the plaintiff's claim is dismissed as it is without merit. It is so decided as per Disposition.
